Oxyfuel Coal Combustion Power Plant System Optimization
Oxyfuel-firing of a steam boiler is a low risk high-efficiency technique for CO2 capture in a power plant. Oxyfuel-firing can be readily adapted to a new power plant or to retrofit applications. Development and design of pulverized coal and circulating fluidized bed oxyfuel boilers and balance of plant equipment have been conducted to identify the required specific features, which will maximize...
متن کاملSystems Analysis of Ionic Liquids for Post-combustion CO2 Capture at Coal-fired Power Plants
The main objective of this study is to investigate the feasibility and costs of ionic liquid (IL)-based CO2 capture systems at pulverized coal-fired (PC) power plants. The IL selected for this assessment is trihexyl(tetradecyl)phosphonium 2-cyanopyrrolide ([P66614][2-CNpyr]), achieving a 1:1 and reversible chemical reaction between [2-CNpyr] and CO2. A multi-stage equilibrium-based modeling fra...
متن کاملControl of a post-combustion CO2 capture plant during process start-up and load variations
Dynamic and flexible operation of a carbon capture plant is important as thermal power plants must be operated very flexibly to accommodate large shares of intermittent energy sources such as wind and solar energy. To facilitate such operation, dynamic models for simulation, optimization and control system design are crucial. In this paper, we present a dynamic mathematical model for the absorp...
متن کاملProcess Integration in Coal based Oxy-Combustion Power Plants
The oxy-combustion technology is ready for demonstration [1]. However, the energy penalty and investment cost related to CO2 capture are still too high to implement this technology in the power industry. The thermal efficiency penalty is currently around 10% points, and as discussed in [2] it is commonly expected to be reduced to below 6% points in the near future. Improvements on the sub-units...
متن کاملCO2 CAPTURE OPTIONS FOR AN EXISTING COAL FIRED POWER PLANT: O2/CO2 RECYCLE COMBUSTION vs. AMINE SCRUBBING
The existing fleet of modern pulverized coal fired power plants represents an opportunity to achieve significant greenhouse gas (GHG) emissions in the coming years providing efficient and economical CO2 capture technologies are available for retrofit. One option is to separate CO2 from the products of combustion using conventional approaches such as amine scrubbing. An emerging alternate, commo...
